ŠUTARA J. (2014): Anatomical structure of pores in European species of genera Boletus s.str. and Butyriboletus (Boletaceae). [Boletaceae, anatomy, pores, cheilocystidia] Czech Mycology 66(2): 157-170 (published: 23rd December, 2014)
abstract
One of the characteristic features of European species of genera Boletus s.str. and Butyriboletus is a conspicuous development of their cheilocystidia covering their pores in youth. The development of this type of cheilocystidia is partly supported by the growth of hyphae of the hymenophoral trama under the cheilocystidia. This special arrangement of cheilocystidia is an important diagnostic character distinguishing European species of the above-mentioned genera from other groups of boletes in Boletaceae. The microscopical structure of this type of pores is described in detail.
ŠUTARA J., JANDA V., KŘÍŽ M., GRACA M., KOLAŘÍK M. (2014): Contribution to the study of genus Boletus, section Appendiculati: Boletus roseogriseus sp. nov. and neotypification of Boletus fuscoroseus Smotl. [Boletus roseogriseus sp. nov., Boletus fuscoroseus, morphology, molecular phylogeny, neotypification, distribution] Czech Mycology 66(1): 1-37 (published: 4th June, 2014)
abstract
The paper deals with Boletus roseogriseus and Boletus fuscoroseus, two closely related species of the genus Boletus, section Appendiculati. B. roseogriseus is described as a new species based on a morphological and molecular study of collected material. B. fuscoroseus, validly published by Smotlacha in 1912, has been often incorrectly named Boletus pseudoregius. This name, however, does not have priority because B. pseudoregius was validly published as late as 1988. In order to contribute to clarification of some controversial questions concerning B. fuscoroseus, the authors have selected a neotype for this species. Descriptions of B. roseogriseus and B. fuscoroseus are accompanied by results of a molecular study (ITS and LSU rDNA sequences) and a discussion of characters distinguishing these species from other representatives of section Appendiculati.
ŠUTARA J. (2008): Xerocomus s. l. in the light of the present state of knowledge. [Boletaceae, Xerocomus, Xerocomellus, Hemileccinum, generic taxonomy, anatomy, histology] Czech Mycology 60(1): 29-62 (published: 4th July, 2008)
abstract
The definition of the generic limits of Xerocomus s. l. and particularly the delimitation of this genus from Boletus is very unclear and controversial. During his study of European species of the Boletaceae, the author has come to the conclusion that Xerocomus in a wide concept is a heterogeneous mixture of several groups of species. These groups are separated from each other by different anatomical and some other characters. Also recent molecular studies show that Xerocomus s. l. is not a monophyletic group. In agreement with these facts, the European species of Xerocomus s. l. whose anatomy was studied by the present author are here classified into the following, more distinctly delimited genera: Xerocomus s. str., Phylloporus, Xerocomellus gen. nov., Hemileccinum gen. nov. and Pseudoboletus.Boletus badius and Boletus moravicus, also often treated as species of Xerocomus, are retained for the present in the genus Boletus. The differences between Xerocomus s. str., Phylloporus, Xerocomellus, Hemileccinum, Pseudoboletus and Boletus (which is related to this group of genera) are discussed in detail. Two new genera, Xerocomellus and Hemileccinum, and necessary new combinations of species names are proposed.
ŠUTARA J., SKÁLA E. (2007): Boletus marekii, a new species with truncate spores from the Boletus chrysenteron group. [Boletus marekii spec. nov., Boletus subgen. Xerocomus, Boletaceae, Czech Republic] Czech Mycology 59(1): 11-24 (published: 28th June, 2007)
abstract
Boletus marekii, a new species which was found in northwestern Bohemia (Czech Republic), is described. This species, belonging to the Boletus chrysenteron group (Boletus subgen. Xerocomus), is characterised mainly by its xerocomoid appearance, red-coloured, soon coarsely rimose-areolate pileus and smooth, truncate spores. Characters distinguishing Boletus marekii from other species of this group, e.g. Boletus armeniacus, Boletus rubellus, Boletus porosporus, Boletus fennicus, Boletus ripariellus and Boletus declivitatum, are discussed. A new combination, Boletus fennicus, is proposed.
ŠUTARA J., ŠPINAR P. (2006): Boletus kluzakii, a new species related to Boletus radicans. [Boletus kluzakii spec. nov., Boletus sect. Calopodes, Boletaceae, taxonomy, Czech Republic] Czech Mycology 58(1-2): 31-42 (published: 10th August, 2006)
abstract
A new species, Boletus kluzakii, which was found in southern Bohemia (Czech Republic), is described. Typical characters of this bolete are: pileus when young whitish or pallid, sometimes with a slight pinkish tint, then more or less rose-pink or purplish pink, at times even purple-reddish in some places; pileus surface conspicuously reddening when handled or bruised; hymenophore yellow, bluing when bruised; stipe yellow with a yellow reticulation; context under pileus cuticle red or purplish red but in other parts of the pileus and in upper half of the stipe pale yellowish or vivid yellow, turning blue when injured; taste bitter. Characters distinguishing Boletus kluzakii from Boletus radicans (the most closely related species) and from other boletes with a pinkish or reddish shade of pileus (Boletus regius, B. fuscoroseus, B. speciosus, B. pulchrotinctus, B. roseoolivaceus, B. roseopurpureus and B. pulchriceps) are discussed.
ŠUTARA J. (2005): Central European genera of the Boletaceae and Suillaceae, with notes on their anatomical characters. [Boletaceae, Suillaceae, generic taxonomy, anatomical characters] Czech Mycology 57(1-2): 1-50 (published: 31st August, 2005)
abstract
A taxonomic survey of Central European genera of the familiesBoletaceae and Suillaceae with tubular hymenophores, including the lamellate Phylloporus, is presented. Questions concerning the delimitation of the bolete genera ar ediscussed. Descriptions and keys to the families and genera are based predominantly on anatomical characters of the carpophores. Attention is also paid to peripheral layers of stipe tissue, whose anatomical structur ehas not been sufficiently studied. The study of these layers, above all of the caulohymenium and the lateral stipestratum, can provide information important for a better understanding of relationships between taxonomic groups in these families. The presence (or absence) of the caulohymenium with spore-bearing caulobasidia on the stipe surface is here considered as a significant generic character of boletes. A new combination, Pseudoboletus astraeicola (Imazeki) Šutara, is proposed.
